WILLIAM VOGEL, OF CHICAGO, ILLINOIS, ASSIGNOR, BY DIRECT AND `MESNE ASSIGNMENTS, TO TI'IE VOGEL PETROLEUM HEATING COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 416,876, dated December 10, 18.89.

Application nea August 5, 1386, semi No. 210,046. (No model.)

` Illinois, have invented certain new and useful Improvements in Oil-Burning Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to apparatus for burning oil in stoves, furnaces, and heaters. Its object is to provide improved construction in such apparatus; and it consists in the matters hereinafter set forth and claimed.

The accompanying drawings illustrate only two ofmany possible adaptations of the burning devices-namely, one suited to a cooking-stove and the other to a heating-stove; but other modications of the invention have been made, adapting it to heating air in furnaces, car-heaters, &c., and to other situations.

In said drawings, Figure l is a central vertical section running from front to rear of a cooking stove, shown in perspective, and containing that form of my improvement in oilburners which is preferred for this partie` ular use, together with a perspective view of one form of automatic oil-feeding devices. Fig. 2 is a vertical section of the oil-burning chamber shown in the stove of Fig. l, looking from the rear to the front of the stove, said section of Fig. 2 being taken transversely to the stove'or lengthwise of the burning-chamber and in a vertical plane at the rear of the slide when the latter is drawn to its eXtreme y application in a cooking-stove of the description there shown, A is an oblong rectangular box of cast-iron, havingits sides and bottom cast in a single piece, or without joint and without a top. On one or more of :its sides is a series of openings a a, Fig. l, (indicated by dotted lines in Fig. 2,) over whichis placed a similarly-apertured slide A', Fig. 1, serving as a damper or register and provided with a handle a', projecting through the side of the stove, by which it may be operated. n

B is a smaller rectangular open-topped and relatively shallow cast-iron box provided with legs b, which support it from the bottom of the box A, and also provided with studs Z2 upon the upper surface of its bottom.

C is a cast rectangular frame without bot tom or top, still smaller than the box B and standing within the latter, being provided with short legs c at the corners to aord a At c a space or passage is shown between passage beneath it. the frame C and the upper edge of the boX B.

D is a vertically-perforated bed, which may be of cast-iron, but which is preferably of porous material-say of tire-brick or asbestusfilling or nearly filling the opening in the bottom of the frame C and resting uponthe studs b.

E is a centrally-open top `plate tted to the box A and provided with a deep flange E around the rectangular .opening c `which iange depends within the box B, but desirably not so far as the level of the upper edge of said box. There is a space e provided between the fiange E andthe frame C, and said frame C does not rise to the top plate E. The said frame C and plate E, provided with a flange E in the instance illustrated, together form a bnrner-casingw-that is to say, said chamber, within which Walls is for-med a fspace or passage e for the iniiuX of air to the combustion-chamber. Air admitted through the register-passages a a may therefore rise :through the outer passages or space a2 and lpass down the passages `e to the upper surface of the bed D, and may thence rise through the central opening e of the top plate.

F is a slide of suitable size to cover the opening e and fitted tolnove back and forth on the top plate E, being guided in its movement by ribsf, ruiming in grooves c2.

F is a rod or handle which projects through the front plate of the stove, by which the slide F may be operated.

F2 is a passage (shown in the form of a tubularappendage of the slide F) extending back between the top plate of the stove and the oven-plate to a point near the outlet-flue G of the stove. Said tube F2 is provided with a downward extension f of its passage,

leading through the slide F, just within the line ofthe rear margin of the latter, as shown in Fig. 2, whereby when said slide is drawn forward so as to cover the opening e said opening c will have comm unication with the space between the upper part of the casing A and the surrounding walls of the stove.

I is an inlet-pipe leading from a source Jl of oil-supply and delivering into the inner box B, as seen in Fig. 2.

K is a valved outlet-pipe leading downward from the bottom of the outer box A.

Describing next the operation of the burning devices here illustrated and above pointed out, oil is admitted to the box B through the pipe I under control either of the hand or of suitable automatic regulating devices. The oil so admitted is preferably sufficient in quantity to enter the perforations cl of the bed D,which in the continued operation of the re becomes highly heated. The oil being ignited, the flame therefrom is supplied with oxygen by the air admitted through the register-openings a a and passages e', and said flame ascends in the space e. If the slide F be pushed back, so as to give egress to the flame, the latter will rise through the opening thus afforded and pass back beneath the top plate of the stove; but if the slide be drawn forward, so as to close the opening e, the fiame and products of combustion will rise through the passage f and pass back through the tube F2 to the outlet-flue G. The volume of the air-supply and will be burned.

The pipe K serves to occasionally draw off the tar-like residuum which will accumulate in the bo`x B from burning heavy oils. The air for supporting combustion in its passage through the space c moves over the surface of the flange E', which, being very hot, raises the temperature of the air, so that it makes itsV exit from the said passage in a heated state, with the effect of facilitating the rapid and complete combustion of the oil. The flange E not onlyl serves to heat the air passl and 2. case shown to be located in one of the Walls ing through the passage c', but also acts to deflect or carry the air downwardly to a point near the top of the porous or perforate bed, thereby supplying the air at a place most favorable for the perfect combustion of the oil rising through the bed.

Next describing the construction shown in Fig. 3, which is a desirable form ofthe burning devices of myinvention, suitedto be inserted in the familiar circular form of heating-stove there shown, it will be first observed that provision is in this case made for directing the flame against the lateral heatingplate of the stove, and that to this end the air is admitted through a central space instead of through a surrounding Vor lateral space, as in Fig. l.

As an incident to the form of this stove, the various castings entering into the burner in this adaptation of the device are shown circular instead of rectangular. provided with a central tube A3, open at the bottom an d top, and a top plate E2, having an annular form, of the depending flange E3 sets over this tube to deflect the air which passes through the suitable side openings d3 at the upper part of the tube A2 downward to the lower part of the fire-chamber. The box B2 is also annular in form and has a tubular inner Wall B3 surrounding the tube A3, desirably at a little distance therefrom, as shown. The frame C2 is in this case constructed with a flange C3, which rests on the outer wall of the box A2, since the air being admitted at the middle of the device, there is no need of the space at the upper edge of this frame C2 to admit the air, as in Figs. 1 and 2. The perforated bed D is of course annular as an incident to the central air-feed: The circular and vertically-movable plate F3 answers to the slide F of Fig. l and its vertical tubes F4 to the tube F2 of Fig. l,terminating near the outlet-fine G of the stove. The plate F3 of Fig. 3 extends over the flange C3, and by its vertical movement may be made to open or close the passage e3, by which the llame escapes froni the combustion-chamber into the general interior of the stove.

F5 is a rod for lifting and lowering the plate F3, said rod being connected with a central vertical guide-tube f2 on the plate F3 by a fastening at f3, and provided with a screwthreaded hand-nut F( above the top plate of the stove. The plate E2 is provided with a vertical projection e4, which enters the guidetube f2, and thereby keeps the plate F3 hori- Zontal, and said projection is shown to be square in cross-section and fittedloosely to a correspondingly-shaped interior of the guidetube f2 as a means of keepingthe plate F3 from rotating when the hand-nut FG is turned. The same passage (in this case lettered c2) is provided betweenthe edge of the box B2 and the frame C2, and a similar feed-pipe I and discharge-pipe K are employed, asin Figs. The air-register a3 A4 is in this The box A2 is IOO IIO

416,876 l y s` of what is' commonly the ashbox of coal-` Ystoves of this form,and the inwardly-project-v ing iiange'H serves to cutfoff f this air-entrance chamber from the general interior of the stove, to which'the iiame passes from the opening c3.

From the two illustrations of the oil-burning devices of my invention furnished by theA figures above described it is evident that formal varieties of said invention may be made without departure from its essential principle. These drawings, in fact, show the burning devices applied to stoves not originally constructed for them. When the stove structure is specially contrived for the burner, certain parts*as the outer box A of Fig. 2 and the tube F2 may manifestlybe made part of the main stove structure. l

Certain forms and adaptations of the invention not here illustrated will be shown iii other applications for patents and will furnish the subjects of claims in such separate patents.

The particular form of burning device illus- .trated in Fig. 3 is described and claimed in a separate application for patent, Serial No. 210,047, iiled simultaneously herewith.

It is to be particularly noted that the bed D mayconsist of a body of sand occupying the ent-ire width of the box B and rest-ing on its bottom. The interstices of the sand body will answer to the perforations d and the space beneath said bed when of brick, as shown.

Any suitable or preferred means for regulating the supply of oil to the burner or {irebox may be employed in connection with the oil-burning apparatus above described. In Fig.,l, for instance, J is a vessel into which any desired quantity of oil may be poured, and which flows through a pipe J to the vessel.J2, andtlience through the pipe I to the burner. Said vessel .l2will in this instance be provided with an electrical controlling device adapted to operate a valvev controlling theinilow of oil from the pipe J through its branch j. Y
